5 0

Answer:

I am not sure what are we supposed to do but I guess we have to solve it?

0=0

Step-by-step explanation:

first rearrange the formula to get all r's on one side so it's gonna be:

4r-4r=-15+19-4

we really come to a closed end here because 4r-4r=0  

it's gonna be 0=-15+19-4

0=0

Mkae sure you copied the question correctly

p.s: I'm not sure

Someone please help me will give BRAILIEST!!!!!

The graph here displays a constant rate of change. Rate of change is another word for slope. Because the slope does not change it is constant (the same) throughout. If it were a curved line, like in a parabola, it would be a variable rate of change since the slope changes.

The answer is constant.


Let me know if I can help further.

If u(x) = x5 – x4 + x2 and v(x) = –x2, which expression is equivalent to (U divided by V) (x)
Goryan [66]
To find the equivalent of the equations U divided by V where as u(x) = x^5 - x^4 + x^2 and v(x) = -x^2, first you have to factor out the U first and came up with (x^2)(x^3-x^2+1) then divide it by -x^2 which cancel the X^2 and the answer would become -(x^3-X^2+1), i hope you are satisfied with my answer
